Authors performed pachymetry on 30 normal corneas with Zeiss-Opton, Haag-Streit optical and Paxial 6.1 (Alcon) ultrasonic equipment. Central corneal thickness was 530.00 +/- 29.83 um with Zeiss-Opton, 524.50 +/- 22.53 um with Haag-Streit and 536.70 +/- 30.15 um with ultrasound pachymetry. Pachymetric data showed no changes with increasing age, with sex and right and left sides.
